ROCKS OF SOUTH DEVOW^. 499 



My first discovery in the Cockington Beds was a fragment of 

 Homalonotas in red slaty beds in Seaway Lane, Cockington. 



The subdivision of the Lower-Devonian Beds of the Torquay and 

 Paignton area into Upper and Lower Coblenzian is not justifiable, 

 the districts being too much disturbed to furnish a certain succes- 

 sion ; very detailed investigation in the Torquay district would, 

 however, probably settle this question ; all that can be said so far 

 is that the Middle-Devonian slates pass downwards into Lower- 

 Devonian slates, and these, through intercalation with grit, into 

 the Lincombe, Warberry, and Cockington Sandstones ; but whether 

 the main mass of the Meadfoot beds are below these grits or not, 

 depends on the existence of a dislocation of sufficient magnitude to 

 cut out the latter on the coast near Hesketh Crescent, and this I 

 consider to be probable.

1. Eifelian. — The Warberry beds near Ellacombe, and the Cock- 

 ington beds near Westerland and in Berry Park, are bounded by 

 grey slates, generally irregular, which contain distorted fossils in 

 lenticles. StreptorJiyncJms is common in these beds, and Spirifer 

 speciosus is by no means rare : the Zaphrentidc^^ in a crushed con- 

 dition are also frequent, as well as Phacops latifrons. The more 

 usual type of these slates is exhibited in the cliffs of Mudstone Bay, 

 near Hope's l^ose, and in Daddyhole Cove. In their upper part 

 they contain limestone lenticles, and frequently pass up into the 

 limestone throuo-h thin-bedded limestones, calcareous slates, and 

 slaty limestone, representing the Calceolen-Kalk. 



Speaking of the relation of the Cockington beds to these slates, 

 we find amongst the unpublished notes of Mr. Champernowne the 

 following passages : — 



" The same beds form Staddon Heights and Mount Edgecombe 

 in Plymouth Sound, and, as Dr. Hoil has shown, they also support 

 the Paignton Trias, rising on opposite sides into the high ground of 

 Windmill Hill and Westerland Beacon ; and they must be many 

 hundred feet thick around Cockington, but are too disturbed to form 

 any estimate from." — " Wherever the sequence is anything like 

 complete the last beds appear to x^ass down by an easy transition 

 into bluish slaty shales, which are well exposed in road-cuttings and 

 small quarries in Berry Park. Nevertheless good sections at the 

 junction are exceedingly rare, and certain local appearances would 

 lead to a belief in more or less unconformity between the two, or 

 even a complete covering-up of the bluish slates . . . Eossils, almost 

 entirely in the state of casts, are fairly common. Streptorliynchiis 

 umbra cidu7n, much distorted, is common near Berry Castle ; and in 

 the same beds at Dartington, at the former locality, I found a cast 

 of Kliynclionella caboides.''' 



The above passages represent the evidence of stratigraphy. At 

 Lower Westerland Berry-Park slates occur, apparently underneath 

 red Lower-Devonian slates, the anomaly being probably due to
